GlowShift’s Black 7 Color Series BAR Boost/Vacuum Gauge With Clear Lens is imperative for anyone that is running a factory or aftermarket turbo or super charger, and prefers their gauge readings are displayed in the metric standard of BAR rather than PSI. This mechanically operated turbo boost gauge will monitor your vehicles compression and boost levels from -1 to 2 BAR ensuring that your turbo does not over boost causing major damage to your engine. Included with this boost pressure gauge is a t-fitting and 6 feet of vacuum hose allowing you to easily tap any vacuum line that is connected to your intake manifold for an effortless installation. GlowShift’s Boost/Vacuum Gauge boasts some incredible features such as an illuminated red needle, a magnified lens that ensures all readings easily monitored, as well as our 7 color through dial LED lighting system. Our through dial LED lighting system allows you to easily select and change the color of the numbers and ticks on your gauge face by simply pressing a button that is located on the front of the gauge. Featuring 7 solid color modes and 2 color cycle modes, this gauge will let you match your factory dash lights or add your own personal style to the interior of your vehicle. With a color memory feature built into each gauge, you won’t have to worry about changing the color of the gauge every time you power up your vehicle, and with the new dimmer feature you can connect this gauge to your headlight switch allowing it to dim 30% when your headlights are turned on for better visibility while driving at night. GlowShift stands behind all of its products by including free lifetime technical support and a one year limited warranty with every gauge purchase.
